# Aider chat conversation:
USER: implement `mark_aider_lines` to print out the file marking any line which was introduced in an aider commit
ASSISTANT: Here are the changes to implement `mark_aider_lines` in `scripts/blame.py`:
scripts/blame.py
```python
<<<<<<< SEARCH
if __name__ == "__main__":
mark_aider_lines(sys.argv[1])
=======
import sys
def mark_aider_lines(filename):
aider_commits = set(get_aider_commits())
with open(filename, "r") as f:
lines = f.readlines()
for i, line in enumerate(lines, start=1):
result = subprocess.run(
["git", "blame", "-L", f"{i},{i}", "--porcelain", filename],
capture_output=True,
text=True,
check=True
)
commit_hash = result.stdout.split(" ")[0]
if commit_hash in aider_commits:
print(f"* {line}", end="")
else:
print(f" {line}", end="")
if __name__ == "__main__":
if len(sys.argv) != 2:
print(f"Usage: {sys.argv[0]} <filename>")
sys.exit(1)
mark_aider_lines(sys.argv[1])
>>>>>>> REPLACE
```
This implements the `mark_aider_lines` function to:
1. Get the set of aider commit hashes using `get_aider_commits()`
2. Read in the lines of the specified file
3. For each line:
- Use `git blame` to get the commit hash that last modified that line
- If the commit hash is in the set of aider commits, print `*` before the line, else print spaces
4. Print out each line, prefixing with `*` if it was last modified by an aider commit
It also adds a check to `__main__` to validate the command line arguments and print a usage message if a filename is not provided.

ASSISTANT: To fix the undefined name errors for `commits`, we need to initialize it before using it in `get_aider_commits()`. Here are the changes:
scripts/blame.py
```python
<<<<<<< SEARCH
def get_aider_commits():
"""Get commit hashes for commits with messages starting with 'aider:'"""
=======
def get_aider_commits():
"""Get commit hashes for commits with messages starting with 'aider:'"""
commits = []
>>>>>>> REPLACE
```
scripts/blame.py
```python
<<<<<<< SEARCH
commits.append(commit_hash)
return commits
=======
commits.append(commit_hash)
return commits
>>>>>>> REPLACE
```
The key changes are:
1. Initialize `commits` to an empty list at the start of `get_aider_commits()`
2. Remove the extra blank lines before the `return commits` statement
This should resolve the undefined name errors, since `commits` will now be properly initialized and in scope when it is used.
